How it works

How it works

Dyphylline belongs to a class
of drugs called methylxanthines. A class of drugs is a group of medications
that work in a similar way. These drugs are often used to treat similar
conditions.

Dyphylline
works by opening up the air passages of the lungs (bronchial tubes). It also increases
the flow of air through them. This helps your breathe better.

People with seizures

Pregnant women

Dyphylline
is a category C pregnancy drug. That means two things:

shown adverse effects to the fetus when the mother takes the drug.

There haven’t been
enough studies done in humans to be certain how the drug might affect the
fetus.

Talk to your doctor if you’re pregnant or plan to become pregnant. This drug should be used only if the potential benefit justifies the potential
risk to the fetus.

Women who are breast-feeding

Dyphylline passes into breast milk and may cause side effects in a child
who is breastfed.

Talk to your doctor if you breastfeed your baby. You may need to decide
whether to stop breastfeeding or stop taking
this medication.

For seniors

Older adults may process drugs more slowly. A normal adult dose may cause levels of this drug to be higher than normal in your body. If you’re a senior, you may need a lower dose or a different schedule.

All possible dosages
and drug forms may not be included here. Your dosage, drug form, and how often
you take the drug will depend on:

your age

the condition being treated

how severe your condition is

other medical conditions you have

how you react to the first dose

What are you taking this medication for?

Asthma and other lung diseases

Brand: Lufyllin

Form: Oral tablet

Strengths: 200 mg, 400 mg

Adult dosage (ages 18–64 years)

The standard adult dosage is up to 15 mg/kg of body weight taken by mouth once every six hours. Your doctor will decide your dose based on how severe your lung disease is and how well you respond to treatment.

Child dosage (ages 0–17 years)

This medication hasn’t been studied in children. It shouldn’t be used in people younger than 18 years.

Senior dosage (ages 65 years and older)

The kidneys of older adults may
not work as well as they used to. This can cause your body to process
drugs more slowly. As a result, more of this drug may stay in your body
for a longer time. This increases your risk of side effects.

Your doctor may start you on a lowered dose or a
different medication schedule. This can help keep levels of this drug from
building up too much in your body.

symptoms or to monitor how well your lungs are working with a peak flow meter.
